Implementations

impl Mesh2D

pub fn new(renderer: &mut GpuRenderer, render_layer: u32) -> Self

Creates a new Mesh2D with rendering layer.

pub fn unload(&self, renderer: &mut GpuRenderer)

Unloads the Mesh2D from the Instance Buffers Store.

pub fn set_order_override(&mut self, order_override: Option<Vec3>) -> &mut Self

Updates the Mesh2D’s order_override.

pub fn from_builder(&mut self, builder: &Mesh2DBuilder)

Clears and Builds Mesh’s from the Mesh2DBuilder into the Mesh2D.

pub fn append_from_builder(&mut self, builder: &Mesh2DBuilder)

Appends Mesh’s from the Mesh2DBuilder into the Mesh2D.

pub fn clear(&mut self)

pub fn set_position(&mut self, position: Vec3) -> &mut Self

Sets the Mesh2D’s Position.

pub fn set_size(&mut self, size: Vec2) -> &mut Self

Sets the Mesh2D’s width and height.

pub fn create_quad(&mut self, renderer: &mut GpuRenderer)

Updates the Mesh2D’s Buffers to prepare them for rendering.

pub fn update(&mut self, renderer: &mut GpuRenderer) -> OrderedIndex

Used to check and update the vertex array. Returns a OrderedIndex used in Rendering.

pub fn check_mouse_bounds(&self, mouse_pos: Vec2) -> bool

Checks if Mouse position is within the Mesh2D’s Bounds.
